Filed: 1924-01-24
Abstract: 232,689. Gramophone Co., Ltd., and Buckle, H. L. T. Jan. 24, 1924. Diaphragms not associated with tonearms. - Relates to gramophones of the kind in which the diaphragm i s so mounted that it occupies a vertical position when in use and can be turned to lie parallel with and close to the turntable when out of action. According to the invention, which is particularly applicable to machines having a diaphragm comparable in size to that of the record, the diaphragm is pivotally supported by a member which is adapted to turn about an horizontal axis on an horizontally swinging member, the latter being mounted on a plunger which' can be raised or lowered as required. The plunger 3, which is tubular, is mounted in a fixed sleeve 2, and, when the gramophone is in use, is held in the raised position shown by a spring catch 6. Pivoted on ball bearings 9 in the plunger is an horizontally rotatable member 10, 12 on which is mounted by means of an axially rotatable horizontal bolt 14 the diaphragm supporting member 13, 18. The bolt 14 is secured to the part 13 by a set-screw 13', and is held in place by lock-nuts 15, a flat face on the part 13 being drawn into contact with a similar face 12' on the portion 12, a friction washer being also provided. The part 18 is a depending arm, having bearings 19 for pivots 20 on the diaphragmholding ring 22. A spring 28, the tension of which is adjustable, serves to regulate the pressure of the needle on the record. Forward and backward rooking movement of the diaphragm ring on its pivots is limited by a stop pin 23 and the front of the part 13 respectively. When not required for playing, the diaphragm support 13, 18 is rotated through a right angle about the axis formed by the bolt 14, the rotary movement being limited by a screw 16 engaging with an arcuate slot 17 in the part 12, and a ball catch 35 holding the member 13 in either of its extreme positions. The plunger 3 is finally depressed to bring the diaphragm to the position shown in dotted lines.

IPC: B60T8/52
Filed: 1925-01-23
Abstract: 252,223. Tugwood, R. J., (Daimler- Motoren-Ges.). Jan. 23, 1925. Fluid-pressure.-Means for automatically regulating the pressure applied to the brakes of a vehicle by the relative movement of the frame or body of the vehicle with respect to the wheels or braked parts as described in Specification 189,746 is applied to fluid-pressure brakes. As shown in Fig. 1, the. brake system comprises a cylinder h the piston i of which is arranged to be actuated by a pedal m, lever l and link k to force liquid into a cylinder f containing a piston for applying brake shoes c by a wedge d. The one end of the link h has a pin-and-slot connection with the lever l and is engaged by a bell-crank n connected by a rod p with ,a piston s against which presses a spring u in a cylinder t connected to the chassis. The rod p is connected to parts associated with the axle. If therefore the retarding force acting on the chassis due to the application of the brakes exceeds the tension of the spring, relative forward movement of the chassis takes place whereby the point of connection of the link k with the lever l is adjusted to reduce the pressure transmitted by the pedal to the brakes. In another arrangement as applied to a pneumatic brake system in which air is admitted to the cylin. der f from a storage reservoir, the rod p actuates a relief valve.

Filed: 1960-01-28
Abstract: 917,360. Electric selective signalling systems. MARTIN, W. T. April 25, 1961 [Jan. 28, 1960; March 26, 1960], Nos. 3036/60 and 10780/60. Class 40 (1). [Also in Group XVIII] In a weighing system an unknown weight on a centrally fulcrumed beam is counterbalanced by a gradually increasing known weight and the passage of the beam through the balance condition closes a contact causing the value of the known weight at that instant to be recorded. In each embodiment described the known counterweight comprises a chain or rope which is gradually unwound. In Fig. 1, a chain 13 is initially arranged so that all the slack is in the right-hand loop and an unknown weight is placed in a left-hand scale pan 12. A drive wheel 14 and an associated rotary switch 16 are then driven anti-clockwise thereby applying a gradually increasing counterweight to the weighing beam. When the beam passes through its balance condition it closes a contact 20 which causes a relay associated with the particular contact of the switch 16 marked at that instant to pick-up, thereby recording the value of the counterweight. The drive wheel 14 continues rotating anti-clockwise until all the slack chain is on the left-hand loop. With suitable switching a further weighing operation can then be effected using a right-hand weighing beam as the chain is driven back to its initial position. In a second embodiment (Fig. 3, not shown) for check-weighing a number of similar articles, a reference counterweight, a little less than the lightest article expected, is fixed to the beam and the chain is arranged to run in a liquid whereby the maximum additional load it can apply to the beam just exceeds the permissible tolerance range, and the system is arranged to provide one of three output indications, underweight, accept, or overweight. In a third embodiment, for check-weighing cans of beer, an empty can is weighed on a left-hand beam, as in Fig. 1, to prepare a circuit 75, Fig. 6, via a rotary switch 61, so that when the filled can is weighed on the right-hand beam, causing a rotary switch 62 to mark one of its nine output leads, one of three relays 70, 71 and 72 is pickedup indicating that the can is either correctly filled or under or over filled.

Abstract: 790,037. Hydraulic brakes. GRANT, L. I. H. Jan. 31, 1956 [Feb. 11, 1955], No. 3104/56. Class 103 (1). In an hydraulic braking system for vehicles, two master cylinders 5, 6, operated by a single brake pedal 10, are respectively connected to the front and rear brakes of the vehicle and an equalizing cylinder 17 having a free piston 18 therein is coupled in common to both master cylinders 5 and 6 such that, should leakage occur in one of the hydraulic circuits, the piston 18 will be axially displaced to enable fluid pressure in the remaining master cylinder system to be substantially unaffected. The piston 18 in the equalizing cylinder 17 is provided with circumferential grooves 20 such that when the piston 18 arrives in its fully displaced position in consequence of a partial brake failure the spring loaded plunger 21 will enter one of the grooves 20 and prevent unwanted movement of the piston 8; the movement of the plunger 21 being used to control a switch 22 to illuminate a warning lamp. By using master cylinders of differing diameter and providing the balancing piston with end portions operating in bores of different diameter in the equalizing cylinder, differential braking may be effected, for example, the braking effort applied to the rear wheel brakes may be different from that applied to the front wheel brakes.
